PEX250x1200 Jaw Crusher
When quarry and sand-and-gravel producers feed hard, rounded river pebble and cobble into a crushing line, the machine that takes the first hit decides whether the whole plant stays profitable. The PEX250x1200 jaw crusher is Baichy Heavy Industry's answer to that challenge: a long-stroke, deep-cavity jaw crusher built for continuous primary (and secondary) reduction of abrasive stone. In this guide we cover what the PEX250x1200 jaw crusher does, how it works, its key specifications, and why buyers around the world specify it for pebble crushing.
Why the PEX250x1200 Jaw Crusher Is the Right Primary Crusher for Pebble
River pebble is notoriously hard and abrasive. Its rounded shape, high silica content and sharp wear behavior quickly destroy weak crushers. The PEX250x1200 jaw crusher is designed specifically for this duty:
Deep Crushing Cavity, No Dead Zone
The PEX250x1200 jaw crusher uses an optimized symmetric crushing cavity that holds more rock per stroke. Unlike shallow-cavity small jaw crushers, the PEX250x1200 jaw crusher accepts larger cobbles and moves material downward without blocking.
Long Stroke and High Reduction Ratio
The PEX series fine jaw crusher delivers a longer nip stroke than standard PE models. That means the PEX250x1200 jaw crusher produces a finer, more cubical product on the first pass, reducing the load on downstream cone or VSI crushers.
Heavy-Duty Frame and Manganese Steel Jaw Plates
The PEX250x1200 jaw crusher sits on a welded, reinforced frame that resists the shock of hard cobble. Its jaw plates are cast from high-manganese steel (Mn13Cr2 / Mn18Cr2), so the PEX250x1200 jaw crusher keeps its throughput even as wear progresses.

How the PEX250x1200 Jaw Crusher Works
Inside the PEX250x1200 jaw crusher, an eccentric shaft drives the movable jaw in a reciprocating motion. As the wheel and flywheel turn, the movable jaw moves toward the fixed jaw, crushing pebble by compression; on the return stroke, crushed material falls through the adjustable discharge gap. The PEX250x1200 jaw crusher's toggle plates protect the machine from uncrushable metal by breaking before the frame suffers damage, and the spring release prevents tramp-metal damage.
This simple, proven mechanism is why the PEX250x1200 jaw crusher remains the favorite primary crusher for small-to-medium pebble quarries, construction waste recycling, and mineral processing plants.

Performance Advantages of the PEX250x1200 Jaw Crusher
High Throughput at Low Energy Cost
Thanks to the long stroke and steep nip angle, the PEX250x1200 jaw crusher moves more tons per kilowatt-hour than comparable small jaw crushers. For a pebble plant running two shifts, the PEX250x1200 jaw crusher's low specific energy directly lowers the electricity bill.
Adjustable Discharge for Aggregate Shaping
Changing the discharge setting on the PEX250x1200 jaw crusher only requires shim adjustment, so operators can switch from 25 mm road base to 60 mm coarse aggregate without stopping the line for long. This flexibility makes the PEX250x1200 jaw crusher ideal for plants that sell several aggregate grades.
Cubical Product Shape
A balanced throw on the PEX250x1200 jaw crusher fractures pebble along natural cleavage planes, producing cubical grains that meet concrete and asphalt specifications. Buyers often report that the PEX250x1200 jaw crusher cuts the need for a secondary crusher on small projects.
Easy Maintenance and Spare Parts
Baichy stocks Mn13/Mn18 jaw plates, toggle plates, bearings and side liners for the PEX250x1200 jaw crusher. Lubrication points are grouped, so routine service on the PEX250x1200 jaw crusher takes minutes rather than hours.

Applications Beyond Pebble
Although the PEX250x1200 jaw crusher is famous as a pebble primary crusher, its long list of applications also includes:
Secondary crushing after a PE jaw crusher in granite and basalt circuits;
• Sand and gravel preparation for ready-mix concrete;
• Iron ore, gold ore and copper ore preliminary reduction;
• Construction demolition waste and recycled concrete crushing;
• Coal, coke and shale crushing for small mining operations.
Whatever the feed, the PEX250x1200 jaw crusher adapts through its adjustable discharge and robust wear package.
Operating and Maintenance Tips for the PEX250x1200 Jaw Crusher
• Start empty. Never start the PEX250x1200 jaw crusher under load; the feeder should begin only after the crusher reaches running speed.
• Keep the feed even. Choke-feeding the PEX250x1200 jaw crusher improves throughput but bridging large cobbles causes shock loading.
• Check the toggle and spring. Inspect the toggle plate and tension spring on the PEX250x1200 jaw crusher weekly, and replace them at the first sign of fatigue.
• Monitor bearing temperature. The PEX250x1200 jaw crusher should run below 70 °C; rising temperature usually points to lubrication or bearing wear.
• Flip the jaw plates. When one edge wears, reversing the jaw plates on the PEX250x1200 jaw crusher nearly doubles their service life.
